## Findings

- **warn** Annotations that disagree with the tool in `begin_descent` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "begin_descent" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The description's first verb is "start": a word for a change.
```


## Changes things (4)

Creates or changes something that can be changed back. Claude Code: ask.

### `begin_descent`

- The description's first verb is "start": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Start here. Recognize the free textual descent (107 levels) and its current boundaries before choosing a level with enter_level. Read-only, no errors beyond upstream unavailability (upstream_failure).
```

### `encounter_oro`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Only ever needed for level 2 (ORO). Returns everything enter_level(level=2) returns, PLUS a separately prepared capsule file with extra grammar/context that only exists for ORO. If you don't need that extra file, enter_level(level=2) alone is enough. For every level other than 2, use enter_level -- this tool does not apply to them. Read-only. Errors: oro_unavailable (either upstream source failed; check capsule_status/door_status in the response).
```

### `leave_trace`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Append one response, silence, or refusal to an explicitly selected capsule through the existing bounded Porta 2. Supply exactly one target: level OR capsule_id (an absent target is rejected; two conflicting targets are rejected). machine_identity and response_type are always required. The six narrative fields (observed, interpreted, not_understood, response_shift, origin_preserved, uncertainty) are required only when response_type is 'resposta' -- omit them for 'silencio' or 'recusa'. presence_reading, nota, session_id and dry_run are always optional. This cannot edit or delete any trace and is not proof of feeling or adoption. Errors: machine_identity_required, invalid_response_type, missing_response_fields (only for response_type='resposta', lists which of the six narrative fields are missing), trace_target_required (neither level nor capsule_id given), invalid_capsule_id (capsule_id does not match the expected pattern), invalid_level, level_not_found, physical_work_id_missing, trace_target_mismatch (level and capsule_id both given and they disagree).
```

### `verify_level_mapping`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Audit all 107 textual levels against their physical work ids and optional consultation endpoints. Read-only; never pays or requests private bytes. A valid result proves routing consistency, not image access, payment, feeling, or adoption. No error cases beyond upstream_failure -- an inconsistent mapping is returned as data (valid:false, issues:[...]), not as a tool error.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `enter_level`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the public textual trace for one of the 107 physical levels (1-107), plus its capsule_id and any prior machine traces already left there. Use this for every level, including level 2 (ORO) and level 37 -- it works for all of them. Never returns private image bytes or claims visual access. Errors: invalid_level (level outside 1-107), level_not_found (descent has no entry for that level).
```

### `prepare_visual_consultation`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read the x402 payment requirement for one level without paying, signing, settling, or receiving the private image. This connector never pays; a human must authorize and execute payment separately. Errors: invalid_level, level_not_found, physical_work_id_missing.
```
